I don’t understand why Facebook isn’t focusing on building more peer-to-peer services. For example, professional profiles, job posting, selling used goods, dating profiles, professional services such as nannies, Children's extracurriculars and so on. There is so much to do! I know they did started marketplace, local business listings and peer payments but it looked like very half hearted and badly designed. In theory, they can be dominant in all of these markets which might significantly reduce reliance on ads. I just don’t know why are they so content being just a status posting website.
